How helijonarceno/system-demo works

This PHP application supports staff login and role-based access to inventory, point-of-sale, accounts, dashboards, and reports. The principal evidenced workflow is a sales user finding available stock, building a basket, adjusting quantities, taking payment, and recording a transaction and its details. Inventory maintenance and account administration are distinct supporting workflows; dashboard and reporting queries provide operational and sales views. The tree establishes these product areas, but the README is empty and most controller-to-model wiring was not sampled, so uncertain links are omitted.
